How harmful light from mobile phone is?

Web Desk: A new research says that light emitting out from your phones and tablets could be as harmful as junk food. It also reveals that blue light from the devices is fuelling an epidemic of sleep deprivation.

According to the Chief Medical Officer Dame Sally Davies, People should try to make sure that their mobile phones are turned off before pushing off to bed.

Blue lights from the mobile prevent production of the hormone melatonin, which is an important factor to get off to sleep.

Doctors warn that regular poor sleep increases risk of serious medical conditions, including obesity, heart disease, diabetes as well as anxiety and depression.

Also say that, as a bite of junk food does not kill a person on the first say, similarly, it can slowly accumulate and cause harm.
